Which 68060.library?

[Cosmos Amiga]

A new 68060.library version for Phase5 boards is actually on test here :

 68060.library v46.21

  - v46.20 -> v46.21
  - Removed Cyberpatcher support (users must use the very better OxyPatcher)
  -  Added faster Autovectors (http://leblogdecosmos.blogspot.fr/2012/05/code-optimisation-iii.html)
  - _ffloord optimized (mathieeedoubtrans.library)
  - _fceild optimized (mathieeedoubtrans.library)
  - _fsind optimized (mathieeedoubtrans.library)
  - _fcosd optimized (mathieeedoubtrans.library)

[Cosmos Amiga]

The problem with any optimizations is that it is so easy to get something wrong.

The worst anyone can do on Amiga Classic is doing nothing...

Clever guys help me to improve again and again this library (or other) and stupid guys blablabla on forum...
